Pressure canning is the best way to preserve the flavor of corn. Even though the sugar in sweet corn causes browning, the discoloration does not hurt the food. Recipe copyright 2012 by Eugenia Bone.

- 10 ears corn, shucked
- 3/4 pound fresh lima beans or other shell beans (about 2 1/2 cups shelled)
- 2 1/2 teaspoons coarse salt, divided
Have ready 5 very clean pint jars with new lids and screw-top bands that have been simmered in hot water; keep submerged in hot water until ready for use.
Bring a large pot of water to a boil, and add corn. Cook until tender, about 4 minutes. When cool enough to handle, cut off kernels (do not cut so close to cobs that the milk comes out; you should have 5 cups). Reserve cobs to make corn soup. Combine corn kernels and beans.
Place 1/2 teaspoon salt in each hot empty jar. Fill each jar with 1 1/2 cups hot succotash, leaving 1-inch space at top.
Place rack in a pressure canner, and fill canner with 3 quarts boiling water. Place jars on rack. Align cover handles so they are locked into position according to manufacturer's instructions. Remove pressure regulator from steam vent. Heat canner over high heat. Let steam release from vent 10 minutes, then return pressure regulator to steam vent.
Process corn at 11 pounds pressure 1 hour, adjusting for altitude and type of pressure canner according to manufacturer's instructions.
Turn off heat, and let pressure drop naturally, about 40 minutes. When canner is depressurized (according to manufacturer's instructions), remove gauge, then canner's lid.
Remove jars using tongs, and let cool; you may hear the lids ping, a sign that vacuum sealing has occurred. After 6 hours, check each lid to make sure it is concave (another sign that it's vacuum sealed), then remove screw-top band, and try to remove lid with your fingertips. If you can't, seal is tight. Label and date jars, then store in a cool, dark, dry place up to 1 year (after opening, succotash can be refrigerated up to 1 week). Before using, check to see if lid is still concave; if it isn't, discard.
